Liang-Chi Hsieh updated SPARK-17254: ------------------------------------ Attachment: stop-after-physical-plan.pdf > Filter operator should have “stop if false” semantics for sorted data > --------------------------------------------------------------------- > > Key: SPARK-17254 > URL: https://issues.apache.org/jira/browse/SPARK-17254 > Project: Spark > Issue Type: Improvement > Components: SQL > Reporter: Tejas Patil > Priority: Minor > Attachments: stop-after-physical-plan.pdf > > > From > https://issues.apache.org/jira/secure/attachment/12778890/BucketedTables.pdf: > Filter on sorted data > If the data is sorted by a key, filters on the key could stop as soon as the > data is out of range. For example, WHERE ticker_id < “F” should stop as soon > as the first row starting with “F” is seen. This can be done adding a Filter > operator that has “stop if false” semantics. This is generally useful. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
